A gasket or other comprising a core and a flexible outer layer prepared by co-dispensing at a temperature of about 15° C. to about 30° C., a core composition and an outer layer composition, wherein the core composition is an elastomer or a foam and comprises at least two reactive components, wherein each component has a viscosity at 25° C. of less than 106 cps. The core and outer layer compositions are applied in a non-solid state. The outer layer is preferably at least a two reactive-component elastomer or foam. A method for producing a gasket or other object comprising co-dispensing a core composition and an outer layer composition at a temperature of about 15° C. to about 30° C., wherein the core composition is an elastomer or a foam and comprises at least two reactive components, wherein the composition has a viscosity at 25° C. of less than 106 cps.
A gasket comprising a flexible or rigid core and a flexible or rigid outer layer prepared by co-dispensing at a temperature of about 15° C. to about 30° C., a core composition and an outer layer composition, wherein the core composition comprises at least two reactive components, the composition having a viscosity at 25° C. of less than 106 cps, and the core composition forms a foam or elastomer.
